First of all, the east, west, north, south and middle directions:
Southeast, northwest and middle represent five directions of east, west, south, north and middle, corresponding to five elements, five colors and five seasons. It also refers to four branches and centers in China or a certain country.
In China:

2. The westernmost point: Pamirs (73.5 degrees east longitude);
3. The northernmost point: the center line of Heilongjiang main channel north of Mohe, Heilongjiang (about 53 degrees north latitude);
4. The southernmost point: Zengmu shoal in Hainan Province (about 4 degrees north latitude);
5. The middle, that is, the producing area, is in the middle of Shaanxi Province.
Second, the method of distinguishing the direction of southeast and northwest:
1. southeast northwest formula: upper north, lower south, left west, right east.
2. Identify the direction with a compass, and the initial direction of the compass is set to point to the north.
3. Use the map to determine the direction. Look at the map more on weekdays and get to know the general direction of the subway.
4. Distinguish the direction by the direction of the sun. China is in the northern hemisphere. For most cities in China, it is north of the Tropic of Cancer. The sun rises in the southeast in the morning, sets in the southwest at dusk, and is due south at noon.
5. Use trees to tell the direction. On sunny hillside, please pay attention to sunny hillside. Observe whether there are any trees that have been cut down and see its annual rings. One side of the sparse arrangement of annual rings is the south, while the other side is the north.
